HORSE-POWER- Specification of Letters Patent.

To rtZZ whom it nuty concern:

Be it known that I, JOHN G. MOLE, a citizen of the United States, residing at Batavia, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Horse-Powers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

'lhis invention relates to horse-power machines for driving other machinery, and has for its object to provide a machine of this kind from which a greater amount of power may be obtained proportionately with the weight thereof and the space occupied thereby than is possible under the ordinary arrangement.

A further object is to provide certain construction features for positively retaining the driving-gear mechanism in true alinement, and thereby lessening the liability to get out of order and also reducing the friction to a minimum.

In the drawings, Figure 1 is a plan embodying the improved features. Fig. 2 is a longitudinal section; Fig. 3, a transverse section on line 3, Fg: 2, and Fig. 4 is a plan of a bot tom casting or base.

A represents the different timbers formin a supporting-frame, which will be solidly secured in a stationary position.

The main driving or master gear-wheel B is simply a ring and has no center-bearing or hub and rests on the bearing-surfaces of the stationary base C. This gear-wheel is provided with an overhanging horizontal flange D, as more clearly shown in Fig. 2. The gearteeth are formed on the exterior surface of the wheel below the overhanging flange, as shown in Figs. 2 and 3 and indicated by dotted lines in Fig. 1. The base C is provided at intervals with vertical bearing-sleeves 6, Figs. 3 and 4, on which friction bearing-rollers 7 are loosely mounted. A bolt 8 is inserted up through these sleeves and heads in the under side of the base, as indicated by dotted lines. A lock-nut 9 is screwed down to a bearing on or sleeves 6 and retains the bolt or bolts 8 in their normal position. A guide bearing-plate 10 is loosely mounted on the upper ends of the bolts 8 and is provided :in the under side with a recess 11, Fig. 3, in which the lock-nut 9 is seated, and thereby prevented from working loose. The

I The driving gear-wheel is cut away to form an annular shoulder 16 on the inner upper gear-wheel and its horizontal overhanging edge or junction of the vertical part of the flange. The plate or plates 10 are provided with an extended end 17, which projects over the annular shoulder 16 and stops just short of the vertical wall 18 thereof. The normal position of the overlapping ends of the plates 17 is out of contact; but the adjacent surfaces are so close that the least wabbling of the gear-wheel will bring the surface in contact and the wheel steadied into its true running position. A nut 19 retains the plates 10 in place on bolts 8.

The driving gearwheel engages pinions 20 and 21, located diametrically opposite each other on the longitudinal line of the machine. The pinion 20 is located at that end of the machine from which the power will usually be transmitted, and the driving connections therewith will be first described. The basecasting at this end of the machine is provided with a vertical bearing-sleeve 22, Fig. 4, on which a gear-wheel 23 is loosely mounted. The pinion 20 is rigidly mounted on the upper extended hub 24 of the gear-wheel 23, as shown in Fig. 2, the parts being broken away. A bolt 25 is inserted up through the sleeves 22 from the under side of the base. nut 26 is screwed down on the threaded end of the bolt 25 to a bearing and a locking-cap 27 seated down over the same to prevent its working .loose, the locking-cap being secured by a nut 28, by which means the pinion and its gear-wheel are retained in their proper working position and prevented from iaving a vertical movement. The gear-' I wheel 23 in turn engages a pinion mounted on the driving-shaft 29, provided with suitable ournal-bearings in the base C. A gearwheel 30 is mounted on the outer extended end of shaft 29 and engages a pinion 31, mounted on a stub-shaft 32, j ournaled in the base-casting C. The stub-shaft is provided A lock- 9';
